The general principles of CEP cosmology, even with the addition of the "fast scrambling" hypothesis for equilibration times[1]}, puts only mild restrictions on the form of the slow roll metric. None of the bounds of the "Swampland" program[2]} apply here. It is clear that despite the fact that the formulae relating the metric to data are different in detail, the problem of fitting present day CMB observations with CEP models contains exactly the same freedom as fitting a conventional inflationary potential to the data.
